SUPPORT FOR ELLIPTIC SPRINGS.

SPECIFCATIQN forming part of Letters Patent No. 373,516, dated November22, 1887. Application tiled February 26, 1887. Serial No. 220,065. (Nomodel.)

To all whom it may concern.-

Be it known that I, WESLEY COLE, a citizen of the United States,and aresident of Detroit, in the county of Vayne and State of Michi gan, haveinvented a certain new and useful Improvement in Supporters forElliptical Springs, designed to take the place of Bubber Bumpers; and Ido declare the following to be afull, clear, and exact description ofthe in 1o vention, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of ref` erence markedthereon, which form a part of this specification.

Figure l of the drawings is a representation of this invention, and is avertical section. Fig. 2 is a top View. Fig. 3 is a detail and avertical section taken across the springs.

My invention relates to vehicle-spring supporters; and it consists inthe construction and novel combination of parts, as hereinafterdescribed and claimed.

The object of my invention is to provide a spring-supporting devicewhich is designed to supersede the rubber bumper commonly used withelliptical vehiclesprings to relieve the springs ofthe jar thatisimparted to them in traveling over rough or uneven roads.

InthedrawingsIhaveillustratedthespringsupporter as attached to the lowerhalf ofthe elliptical spring. This disposition ofthe supporter is notabsolutely essential to insure its successful operation, as I may and doinvert the spring-supporter and secu-re it to the upper half of theelliptical spring to accomplish a like result to that secured byconnecting the spring-supporter with the lower halt' oi" the ellipticalspring.

Referring by letter to the accompanying drawings, A designates one ofthe elliptical springs employed to support the vehicle-body upon therunning-gear of the vehicle.

B designates an annular open seat for one end of the spiral spring C.The seat B is made integral with the oppositelyextended horizontal armsD E,which are provided with boltholes F F, through which bolts F arepassed into and through the spring A to secure the spring-seat B to theelliptical spring A. The

annular open seat B is recessed or cut away, as at G, to receive abrace.

C designates a helical coil or spiral spring. In the normally-free end Hof the coil-spring C, I provide a rubber block or plug, I, which is heldin its seat and connected with the elliptical spring by a wire cord, K,one end of which is passed axially through the rubber plug I and tiedupon itself, the other end of said wire cord4 K being passed through ahole in the mid- 6o die of that half ofthe elliptical spring to which itis desired to attach it, and then twisted upon itself to secure it inplace. rI`he rubber plug I assists in taking off the jar,and the wirecord serves to hold the rubber plug I in its place, and also takes theplace of one of the bolts that holds the leaves ofthe spring together.

I may,and sometimes do,use the spring-sup porter without the wire cordand rubber plug; but I prefer to use them in most instances.

Instead of using bolts to secure the supporter to the vehicle-spring, Isometimes use clips. The mode of attachment then is to loosen the nutsthat secure the clips in place and slip the I arms of the socket undersaid clips and again tighten the nuts.

A With the spring-supporter I use a brace, M, which is attached at oneend,by bolts or in any other suitable manuer,to the reach oftherunning-gear, and extends horizontally through 8o the socket B, beneaththe lower enlarged end of the spring C. The width of the end ot" thebrace M is such as to fill the cut-away space G in the base ofthe socketor seat B. rThe bottorn of the seat or socket is largerin diameter thanthe top, and the spring is enlarged at its end to tit the enlargementofthe socket or seat, so that when crowded into the seat by tighteningup the clips the spring will be prevented from rattling. 9o

Having described this invent-ion, what I claim, and desire to secure byLetters Patent, 1s

1. The combination, with an elliptical spring, ofthe open socket or seatprovided with arms secured to the elliptical spring, the spiral springseated in the open socket, and the brace connecting the socket to thereach of the running-gear, substantially as specified.

2. Thecombinatiomwith anellipticalspring, roo

of an open upwardlytapered socket provided the spiral spring, andsecured to the said cush- Io with wings secured to the lower half ofsaid ion, all substantially as described. f spring, this spring andsocket rigidly secured l In testimony whereof I afx mysignature in to anaxle, the brace M, recessed into the base presence of two witnesses.
